WINDOW-CLEANING DEVICE.

To all whom it 'may concern: Y v

Be it known that I, FREDERICK W. Voon- HULL, a citizen of the United States, residing in the city andcounty of Philadelphia, State of Pennsylvania, have invented a new and useful lVindow-Cleaning Device, of which the. following is a specification.

My invention consists of an improved device for wiping the windows of. locomotive cabs, street car .vestibules, automobile windshields'or similar windows from within and without'the necessity of opening the window or getting out of the vehicle.

gl. It further consists of improved means for 1moving the wiping-bar toward and away from the glass pane.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

` For the purpose of illustrating my inven.

tion, I have shown in the accompanying drawings one form thereof which 1s at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention `is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a front elevation of a window and its frame provided with my improved window cleaning. device, seen from the outside. Fig. 2 represents a.' similar view from the inside of the window.

' Fig. 3 represents a horizontal section on the line .fbm in Fig. l. Fig. 4 represents a vertical section on the line g/-g/ in Fig. 1. Fig. 5 represents a perspective detail view of a part of the hanger. Fig. 6 represents an elevation of a window and its frame illustrating a different arrangement of the hanger. Fig. 7 represents a top view of another form of my device. Fig. 8 represents a detail view of a connection for obtaining parallel movement for the arms supporting and actuating the wiper-bar'and for providing yielding support for the same. Fig. 9 represents a lsectional detail View of the pivot connection for an arm and the bracketv on the wiper-bar.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings; the reference numeral 1 indicates the window frame, in which the sash 2, of the window-pane, 3, is mounted. A bracket, 4, is secured to the window-frame or other support, at a suitable point with respect tothe window-pane, and is formed with two vertical sleeves, 5 and 6, in its projecting portion. Bolts, 7 and 8,' pass through said sleeves, and the ends, 9, of the links, 10, are pivoted upon the ends of said bolts. The opposite ends, 11, of said links are pivoted upon'the ends of bolts, 12, passing through sleeves, 13 and 14, in a bracket, 15, projecting-from a bar 16, upon the end of a horizontal sleeve, 17. A rockshaft, 18, is journaled in said sleeve and has a hand-lever, 19, secured to one end, which lever may be engaged and held away to one side of the window by a hooked catch, 20. The horizontal sleeve 17 passes through the window-frame or other support, and has on its end a supporting arm 21, secured to it. An arm 22, is secured to the end of the rockshaft, and a second arm 23 is pivoted upon a bolt or stud 24, projecting from the end of the supporting arm 21. The oppositeends of said arms are pivotally connected with the bracket 26, as here shown by studs 25, said bracket carrying a wiper-bar l27 which is thus held in its proper position in relation to a window-pane when it is moved over the face thereof.

The method of operating this device is substantially the same as that of the device for which application No. 610,218, was filed by me on the 23rd day of February 1911. When it is desired to wipe rain, snow, sleet, or whatever may be deposited upon the window-pane' from the same, the hand-lever 1s released from its catch, and after'rocking it and the rock-shaft to bring the wiper-bar clear of the Window-frame and sash, the hand-lever is pulled toward the operator, swinging the links and drawing the wiperbar against the window-pane, whereupon the hand-lever is swung transversely, causing the wiper-bar to move `over the face of the pane, thus cleaning the same. The outer side of the bracket upon the wiper-bar 1s rounded as at 28, and the holes, 29. through which the pivot-bolts for the arms pass, are

rounded or flared toward bothA sides, so thata certain amountI of play is provide for the wiper-bar, as illustrated in Fig. 9.

In the form ofthe device illustrated in Fig. (l, the arms and wiperbar are on the same side of the window as the links, one arm being secured upon the rock-shaft. and the other arm being pivoted upon a bolt,30, secured in a screw threaded hole, 31, in the end of the bar 16 upon the horizontal bearing-sleeve 17. The hand-lever secured upon the Oppositeend of tlie1.ockshaft. The operat-ion of the device tbe same as that of the first-described device.

In the form of the device illustrated in Fig. 7, the movable ends of the links are pivotedupon boltsl 32, passing through webs, 323, connected by a bar. 31, and having transverse bearing-sleeves, S5 and 36 at their ends.

'Ihe bearing sleeves 533 are fitted upon thek rock-shaft and the arm 2Q secured upon v shaft between said sleeves; A short shaft 3T rocks in the sleeves 3G, and tbe arm Q3 is secured upon said shaft. In this construction the rock shaft 1S, alone, passes through the window frame or other support and has tbe'hand `lever 19 secured thereto as before.

To provide resilient supportfor '-the,l bracket and wiper bar in the'shght rocking motion perrvnitted the same'by their construction and connection illustrated in Fig. 9, the device illustrated in Fig. S of the drawings is employed. link. 3S, is pivoted at itsv ends to the two supporting arms and 2, a distance from thepivoted -ends of the samoand allatsprmff, 39, 1s pivotallv connected to thev bracketl and to said 4link to have swinging movement parallel to the arms, but so asto admit of, but oppose, rocking motion of the bracket. lVhen the wiper-bar is brought against. the window-pane, and theflatter is not in a plane parallel to the plane of movenient of tbe arms, the rounded surface of the bracket, the flared bolt-holes in the sameI and the yielding of spring 39 will permit the wiper to adjust itself to bear with its entire edge against such pane.

the spring will cause it to resume its normal position parallel with the window frame.. The spring will also prevent rattling at the joints between the bracket and the ends of the arms, when the wiper-bar swings on the bolts, thus relieving thelatter from, sudden shock.

The wiper-bar. will be kept out of contact with the window-pane and will notobstruct view through the same when 'notin use, and may be drawn into contact with the pane and exert greater or less pressure upon the same by drawing more orless .upon the hand-lever in moving the same transversely.

The device is applicaole to windows of In said device, a.

IVhen the wiper bar 1s removed from Contact with the glass,`

locomotive cabs, and of thel vestibules .of

d street-cars, to ordinary car-windows, towindows of carriages, -to wind-shields of automobiles, or to any windows or similar transparentcontrivance from which. it is desired te wipemoisture, or any other obstructlon tberefrol'n. The device is operated from within, without' manipulation of the window. It will be noticed that the pivoted links providea substantially rectilinear movement ofthe rock-shaft and of the arms and wiper-bar, so that the latter will be brought .squarely againstl the window-pane to bear equally against the same at all points.. In the several forms disclosed, the same parallel movement is provided 'by means of th Aparallel links.

Attention is directed to the fact that only one small hole or opening, in the support, is necessary, through which the complete operation and control of the wiper bar is accomplished. Any suitable 'means for connecting or supporting the device with respect tol a wind shield in an automobile may be employed.

Having thus described my .invention what lI claim as new and desire-to secure by Let ters Patent.'is: .4
